SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 431,325, dated July 1, 1890.

Application filed November 2, 1889- Serial No. 328,993. (No model.)

To all whom it may concern:

3e it known that I, MARIAN L. BREWER, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new useful Improvements in Shutter-Fasteners, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to the class of devices that are used on shutters for the purpose of securing them in an open or in a closed position; and the object of my invent-ion is to provide a device of this class that shall be simple and compact in arrangement and one provided withmeans located near the inner edge of the blind for locking the latch and also for operating it conveniently.

My invention consists in details of the several parts making up the latch and its operating parts and in'their combination, as more particularlyhereinafterdescribed,andpointed out in the claims.

Referring to the drawings, Figure l is a view in elevation of the inner side of the lower bar of a window-blind. Fig. 2 is a detail top view, on enlarged scale, of a shutter provided with my improved fastener. Fig. 3 is a like view with the front of the case broken away to show construction. Fig. 4 is a detail top View of the fastener, with parts out in section to show construction. Fig. 5 is a detail view in cross-section through the bar of the shutter and in end view of the fastener. Fig. 6 is a View showing the staple.

In the accompanying drawings, the letter a denotes a windowblind or shutter, 12 the lower bar, and c the shutter-fastener as a whole that is attached to the inner side of the lower bar of the shutter, as shown in Fig.1 of the draw ings. The fastener c is preferably made of cast metal, the housing 0' being composed of a part c, that is preferably open on the under side and is provided with the ears or foot portions cl, with the under side flat and lying in the same plane, so as to adapt the fastener to be secured to the flat surface of the windowbar. An integral part of this housing is formedby the tubular extension 0 that is left open on one side in order to facilitate the operation of casting and to more readily receive the latch c, that is held in the latchcase 0 by means of a pivot e, that passes through the walls of the case and serves not only as a pivot, but as a rivet to secure the cover of the case to the body part. This latch-case is made round in outline and projects at about right angles from the under side or back of the housing, the circular shape of the case being preferred as being more readily fitted in place in a hole that may be bored through the bar of the shutter. The latch c has the hooked end c projecting beyond the outer side of the shutter-frame, and a similar hooked end 6 that is located within the housing and does not project beyond the casing on the inner side of the bar 1).

Within the housing 0' there is located a pull-rod f, one end of which is pivotal] y connected to the inner end of the latch e, and the other end projects beyond the end of the housing and furnishes a handle f, by means of which the pull-rod is operated. The handle is preferably formed by bending the rod into a loop form and extending the end f of the rod backward through an opening in the end wall of the housing, and to this end is pivotally attached a swinging lock g. This lock g is pivoted to the side of the endf of the rod and is provided with a thumb-piece g, by means of which the lock may be rotated on its pivot. \Vhen in the position illustrated in Figs. 1 and 2 of the drawings, the end of the swinging lock rests against the end wall 0 of the housing in such position that it prevents the pull-rod from being operated to move the latch. When the lock is swung over, as illustrated in Fig. 3, the rod is left free to move lengthwise within the housing, except for the resistance olfered by the spring h, that is mounted within the housing with one end thrusting against the end wall 0 and the other against a pin or projecting shoulder on the pull-rod. The function of this spring is to hold the latch in such position that it will remain in engagement with the loop or staple "J, one of which is usually fastened to the outer'wall of the building and the other to the window frame or casing in posit-ion to be automatically engaged by the hooked ends of the latch when the shutter is at its extreme open or closed position.

The handle end of the pull-rod of the fastener is located near that edge of the shutter on which the hinges that support the shutter are attached-that is, the end of the pull-rod is in convenient position to be accessible to unlatch the shutter without compelling a reaching out of the window to any inconvenient distance.

The housing of the fastener is so made that it may be attached to the frame of the blind and not present an unsightly appearance, and at the same time will completely inclose all of the operative parts of the fastener except the handle end of the pull-rod, which is, however, preferably located closely against the inner surface of the lower bar of the shutter, so as to enable the fastener to be conveniently secured in place without requiring any change in the ordinary position of the latch, by means of which the blind is fastened in either the open or the closed position.

The bolt g is used to lock the pull-rod and, indirectly, the latch, so that the latter cannot he accidentally unhooked nor intentionally unhooked, when the blind is closed, by any person operating, from outside the blind.

An opening is formed in the wall of the housing directly opposite the inner end of the latch in order that the end of the loop h may be thrust within the housing, so as to engage the end 6 of the latch 6 when the blind is closed. This hook is secured to the window-casing or window-sill by any convenient means, as by a pointed end or by means of a screw, nail, or like device.

I claim as my invention- In a blindfastener, in combination. with the housing 0', having the pull-rod socket e and a latch-case 0 the hooked latch pivotally supported within the case, the pull-rod con nected to the inner end of the latch and with the bent end extending beyond the end Wall of the housing and forming a handle f", the spring h, located within the housing and operating to hold the pull-rod against sliding movement, and the swinging lock g, pivoted to the end of the handle and provided with a thumb-piece g, all substantially as (10- 45 scribed.
